Error 999999: The value type is incompatible with the field type. [OriginID]

Dear UNA team,

first of all thank you for providing this awesome and incredibly helpful tool! Please keep up the great work.

While I have been able to use the UNA tools on the demo data you provide with the toolbox, I seem to be running into an issue when using my very own data. I believe I closely followed the guidelines you outlined in the accompanying PDF and have also been able to iron out some minor issues I ran into thanks to your helpful hints here on the newsgroup.

Yet, now I'm kind of stuck. I'm using UNA on a quite extensive road network (9,204 nodes, 14,709 edges) in Central Tokyo to evaluate the betweenness measures for my buildings regarding the number of people walking from train stations (used as input selection as mentioned here: https://groups.google.com/forum/#!topic/urban-network-analysis/0DpmdzCAbTY). Both the stations ("origins", 223) and the buildings ("destinations", 92,323) are living as point features in the same table. The (pedestrian) road network is a regular ND dataset, created in ArcCataolg as suggested in the UNA documentation.

Here's my error log:

As the network paths in the command reveal that I'm running UNA on ArcGIS 10 inside a Windows XP VM on my OS X 10.8.2 using Parallels 7. Might this cause the problem? Or the spaces in the path (I remember ArcGIS being quite picky about that in the past...)? Or is it just the huge size of my network and OD data?

I'd appreciate any hint that would guide me in the right direction.

Thanks in advance,
Konstantin

Hi Konstantin,

the error suggests that there is a mismatch between one of your input values and a field type in an attribute table. Please check that the following are true:

- your Building ID Field should be an Integer.

- your Building Weight Field should be a positive number.

Pathnames too have caused ArcGIS errors in the past, as a general rule of thumb, it is better to have short path names. We outline in the latest help do online (Sept 16, 2012) that aside from path names, file OD matrix names should not cumulatively add to over a 160-characters.Please see that help section for details.

Lastly, ArcGIS does tend to be more stable on windows systems.

Hope this helps,

Andres
